They are games journalists (sp?) not fanboys, if necessary they will call things stupid when they think it's stupid but harping on shit isn't going to get them anywhere.
There's little to no value in them being as 'angry as us' so to speak, furthermore the internet is known to hype and whine the hell up over stuff. The reality is, if Microsoft announce some kind of game change feature or game - a SHITLOAD of angry people are still going to buy the console. Experienced people know this, smart people know this (Giant Bomb fits that category) if you've been through a console generation or two (or more, like they have) - shit like this happens every time. Company announce bad thing X, gamers cry out in vengeance. Company announces good thing Y, gamers forget.
They get this.
I really can't believe I'm defending Microsoft but apply some common sense here, twirling up a blogesque style frenzy of angry readers isn't going to help GB in the slightest.
They've expressed, displeasure at the DRM but there's no value for them as a business to just close up shop, post giant gif macros and scream like crazy. The reality is bang on, it's very unlikely the policy will change and it's very bad for them and their jobs and future in the industry if they behave incredibly poorly over it.
